Bouchea linifolia A. Gray ex Torrey (1859: 126)

Type (lectotype, designated here):— UNITED STATES OF AMERICA. “ Pebbly bed of the San Pedro ”, 9 July 1851, C. Wright 1509 (NY [00103907!]; isolectotypes BM 000992668!, G 00366575!, GH 00093651”, NY 00103909!, NY 00103908!, P 00713790!, US 01177635!).

Protologue citation:—“Valley of the San Pedro, Western Texas (Nos. 436, 449 and 1509, Wright.)”

Notes:— Gray (1853) noted that plants of Mr. Wright’s collection (No. 449 and 1509) appear to be a new species, B. linifolia , but he did not provide a diagnosis of the new taxon so it was not validly published. Subsequently, Torrey (1859) published the new species based on the collections that Gray had mentioned, and he also cited as syntype the gathering Wright 436. Three sheets belonging to the collection Wright 1509 were found at NY where Torrey studied ( Stafleu & Cowan 1986). Thus, the specimen which shows the best quality of preservation of the important diagnostic features of the taxon is here chosen as lectotype of the name (Art. 9.17 of the ICN, McNeill et al. 2012, McNeill 2014).

Bouchea pseudochascanum (Walp.) Grenzebach (1926: 85) ≡ Stachytarpheta pseudochascanum Walpers (1845: 11) Type (neotype, designated here):— BRAZIL. Rio de Janeiro, “Caminho do Lemo a Copacabana”, 1890, A. F. M. Glaziou 18392 (P

02900800!; isoneotype K 000925074!).

Protologue citation:—“In Brasilia prope Bahiam.”

Notes:— Walpers (1845) described S. pseudochascanum based on a dried specimen collected by an unknown collector in Bahia, Brazil. Walpers’ herbarium was sold after his death and its current location is not known ( Stafleu & Cowan 1988). No specimen of S. pseudochascanum containing any indication of being Walpers’s original material has been found in the herbaria that are known to house some of his type specimens (B, BR, G, GH, and LE). Thus, a neotype is here proposed (Art. 9.7 of the ICN, McNeill et al. 2012). Since no collections from the locus classicus (i.e. Bahia) were located, the neotype is designated in agreement with the material examined by Schauer (1847, 1851) and Moldenke (1940b: 117), which comes from Rio de Janeiro.

After a careful examination of the available material the specimen Glaziou 18392 is here selected as neotype since it is very tipical of this species in its current usage and shows all the morphological features described in the protologue, which clearly distinguish the species from the closely related B. fluminensis : leaf blade coriaceous and rounded, paler beneath and obtuse at apex.
